Hello,
What about Sigma 150-600mm F5-6.3 DG DN OS S - L-Mount???
It has already been addressed several times. The investments in DXO Photolab are starting to be questioned. I already wrote that I have many thousands of pictures which do not look good when developed.
greeting
Thomas
With the Update to 6.1 the profile is there: thanks.
Any chance support for Sigma 20mm f/1.4 DNDG | Art will be added later?
It’s a very good lens for astro but suffers quite a bit from vignette, and maybe a bit of distortion (which is less relevant for astro then).
I see the old DSLR version (HSM) was supported, hopefully the new mirrorless version will also be added.
Hi Marie,
Thank you so much for having added modules for Zuiko 150-400mm F4.5 TC1,25x IS PRO with both TC’s
Always glad to hear
Vic
Yessss!!!
And to prove why it was worth the wait, here is a screenshot of part (just under ⅓) of one of my D100 6Mpx images, adjusted in PL5.6, exported to TIFF and then doubled in size to 24Mpx in Topaz GigaPixel. Then opened in Preview to 100% magnification…
At last! I can assemble this, along with its four companions, into a rather large panoramic.
Hi again, Marie
just installed all new Olympus / OM-D modules, all doing apparently well but I have a small problem with pictures taken with
M.Zuiko Digital ED 150-400mm F4.5 TC1.25x IS PRO with TC x2.0 Zuiko
shot with both TC1.25x AND TC x2.0 (works fine with TC1.25x + TC 1.4x though)
PL6 (or 5) Elite does not invite to download this lens module, nor seem to apply it when installed manually, as if it was not detecting the lens combo,
no matter which camera was used, E-M1X or OM-1
Always pleased to hear
Vic
Hello VicM
Could you please upload a RAW/Jpeg including sidecars on upload.dxo.com under your forum name (instead of the support ticket number) and let me know when ready.
Hello Barbara-S
Thanks for your answer - just uploaded 1 ORF and its sidecar
Keep well
Vic
Currently, DxO supports 91’166 modules on 526 camera bodies.
I suppose that DxO will go beyond 100k modules soon…
Wow, the optical module für RF 15-30 works great! Better than DPP. :-).
Thank you1
Hello @VicM
thanks for sharing your image, it helped to spot the issue:
LensInfo provided by the lens in the Exif is 375-1000mm f/11.2 but the aperture of the image is f/11.0
As f/11.0 is inferior to f/11.2), hat image is not accepted. Images with an aperture superior or equal to f/11.2 should be OK.
We are planning to fix it in the next quarter, but not yet for the next release.
So, you’re putting two converters in a row behind a µ 4/3 zoom lens? 
interesting, after all diffraction will kill a lot of sharpness, no?
Like you, I would think the results would suffer, but as long as he’s happy…

I had to try, Mark 
and put together a wild combo of a Nikkor 500 with 2× Nikon TC, a metabones Nikon F > L-mount adapter and a Sigma 2× TC. Getting a 2000 mm f/22, only usable “wide open” as no electrical thingies are involved. And fully manual focus, of course. With a focus ring optimized for speed, not for accuracy, I had the feeling, 0.1° turn already was too much.
What I found super-interesting (as in “very new for me”) was how much of the dynamic range was lost, simply by adding more glass in between. And the enlargement of some fibres somewhere in this “construction”. Nothing on the sensor, but any particle on one of the many surfaces also gets enlarged.
I once tried a Nikon P1000 with its “24-3000 mm” zoom range (actually 4.25-531 mm, cropfactor is 5.66). It was not worse image-quality and focused faster than I could.
But back to the topic: I need to reconsider my definition of bizarre. If DxO has time to work on lens profiles for this combo, it can be that bad, and the difference between f/11 and f/11.2 as factor for doable and impossible feels like a top secret, highly specific lab. 
Hello Barbara-S
Thanks for your answer.
I am pleased to hear you could spot the issue although I have no idea where this f/11.2 aperture is coming from.
I shot wide open and all my softwares (DxO PL5/6, Adobe Bridge, Lightroom, Photoshop or FastRawViewer) are reporting the theoretical f/11.0 aperture.
Keep well
Hi Joachim and mwsilvers
“works fine with TC1.25x + TC1.4x” is referring to DxO Module being applied, not to pictures shot with combo.
I am mostly shooting bif, handheld, and tried both TCs with/without TC1.25x in my early days with this lens to have an idea of eventual interest for when my joints start to cry for a seat and a tripod, and also from time to time during a complete outing to practice framing and panning with longer focal length.
I see. My experience with about 4 different converters mostly was “equal to crop afterwards”. Might be different with a few prime teles, but Fuji 100-400 + 2×TC missed focus more often, raised ISO due to 2 stops lost for TC. Also, the smaller the sensor, the quicker diffraction blur occurs. In theory it sounds cool, one great tele-zoom and with lower cost X× the focal length.
I just was not able to get a convincing TC shot which looked as good as the non-TC shots. Thanks to your combination idea I also tried 2 TCs, not to make fun out of you, I was just curious how “bad” or whatever that would look. I was expecting worse, to be honest, and I haven’t tried earlier because Nikon TCs (at least 1.7× and 2.0×) can’t be coupled together. Is Olympus’ shake reduction working well with that combo?
No offence.
Olympus IS works more than fine for me (E-M1X or OM-1) and I do not notice any difference when TCs are on or not, which is a little miracle with such long resulting focal length.
Thomas Stirr (https://smallsensorphotography.com/) is regularly using TCs on his M.Zuiko 100-400mm f/5-6.3 with convincing results, imho (look for MC-14 or MC-20 for direct access to articles)
Hi Barbara,
sorry these seem not to solve the problem (adjusting the aperture to a value > 11).
I’ve tried that and the result is the same. It seems like the lens will not be identified correctly.
In DXO metadata it shows only as M.150-400mm F4.5 TC + MC-20, whereas without the internal TC
there is shown M.ZUIKO DIGITAL ED 150-400mm F4.5 IS PRO with TC x2.0 (Micro 4/3).
So maybe DXO PL simply does not recognize the lens? I would appreciate any feedback.
Thanks, André
